Description

Technical Field

[0001] The utility model belongs to the technical field of pneumatic tooling, and specifically relates to a bracket for pneumatic universal tooling. Background Art

[0002] Pneumatic tooling is a tooling equipment that uses compressed air as a power source to achieve various operations such as workpiece clamping, positioning, flipping, and conveying. It is mainly composed of solenoid valves, cylinders, air pipes, and clamping claws. When the solenoid valve is opened, the cylinder and air pipe use air pressure to push the two clamping claws closer to or farther away from each other along the slide on the bracket.

[0003] Due to the different sizes of the clamped workpieces, the distance between the two clamping claws is different, so the brackets used can be divided into small, medium and large. This is especially reflected in the processing of automobile shells. The shape and structure of aluminum plates after stamping and shaping are complex, and it is difficult to clamp them with a single clamping claw. Generally, non-standard tooling is required for processing.

[0004] The bracket and the root of the clamping claw are often fixed by several screws. All the screws need to be unscrewed to remove the clamping claw. Instead, a sleeve is inserted into the root of the clamping claw and then a single screw is tightened to lock it. The calibration screw needs to be inserted into the screw hole at the root of the clamping claw and the screw hole of the sleeve respectively. This is not convenient for quickly disassembling and assembling the clamping claw on the bracket. For this reason, we propose a pneumatic universal tooling bracket. Utility Model Content

[0005] The utility model aims to provide a pneumatic universal tooling bracket, which can quickly calibrate and position two clamping claws without using screws, and can release the lock by pulling the handle, so as to facilitate the rapid disassembly and assembly of the clamping claws on the bracket.

The two flange plates are respectively attached to the upper surfaces of the corresponding bearing plates, and the metal rods of the two adjacent clamping handles are clamped with the limiting grooves. After tightening, the adjacent bearing plates and flange plates are inserted with the positioning step pins, and then the handles of the two clamping handles are lowered. The two ends of the metal rods are used to tighten and lock the adjacent bearing plates and flange plates to fix the two clamping claws. When disassembling and repairing the bracket, pull out the positioning step pin, and then, pull the handles of the two clamping handles upwards and loosen them to release the locking state of the bearing plate and the flange plate, so that the two clamping claws can be removed. The entire disassembly and assembly process of the clamping claws does not require screwing, and the calibration steps are simple.

[0008] Guide slots are provided on the outer sides of the two flange plates at positions between the corresponding two limit slots, and circular ring portions matching the guide slots are integrally installed on the outer sides of the two positioning step pins. The positioning step pins can be pushed horizontally along the guide slots and aligned in a straight line with the tightening position of the adjacent bearing plates, so that they can be quickly put into place.

[0009] The upper surfaces of the two supporting plates are provided with positioning holes at positions corresponding to the two clamping handles. The two positioning holes are respectively adapted to one end of the two positioning step pins, and the annular ring falls into the guide groove to be supported. In addition, the supporting plates and the flange plates are sheared away from each other, respectively pressing against different external positions of the outer sides of the positioning step pins, and locking the positioning step pins through friction.

[0010] A reinforcing plate is fixed on the lower surface of the two supporting plates, and the outer sides of the two reinforcing plates have arcs that are consistent with the edges of the positioning holes, which can increase the structural strength of the two supporting plates at the positions of their positioning holes to improve the overall supporting performance of the bracket.

The two rotating shafts are coaxial and can be actively rotated by using driving elements such as brake motors to change the inclination angle of the supporting plates with respect to the horizontal, so that the clamping claws have freedom on the rotating shaft.

[0012] A coupling in a "U"-shaped structure is fixedly installed between the outer sides of the two rotating shafts, so that the two rotating shafts are fixed and can rotate synchronously.

[0022] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0023] like Figure 1-5As shown, a pneumatic universal tooling bracket includes a base 1, which is composed of a bottom plate and two vertical plates fixedly connected to the two ends of the bottom plate respectively, and a bearing plate 2 and a flange plate 3 are arranged side by side on the upper ends of the two vertical plates. Two clamping handles 4 are fixed on the upper surfaces of the two bearing plates 2 at intervals, and the two clamping handles 4 can use handle-type quick locking pins. The clamping claws and the tooling are fixed by bolts on the two flange plates 3. Two limiting grooves 5 are arranged on the sides of the two flange plates 3 away from each other, and the limiting grooves 5 are adapted to the adjacent clamping handles 4. Positioning step pins 6 are inserted at the positions between the two limiting grooves 5 on the upper surfaces of the two flange plates 3. One end of the two positioning step pins 6 passes through the adjacent flange plates 3 and penetrates the bearing plate 2. When installing, the base 1 is fixed on the production The two clamping handles 4 are pulled upward to the designated position of the line, and the two bearing plates 2 drive the two clamping handles 4 to face upward, and the handles of the two clamping handles 4 are loosened upward, and the two flange plates 3 are respectively attached to the upper surface of the corresponding bearing plate 2, and the metal rods of the two adjacent clamping handles 4 are clamped with the limiting grooves 5. After tightening, the adjacent bearing plates 2 and the flange plates 3 are inserted with the positioning step pins 6, and then the handles of the two clamping handles 4 are lowered, and the two ends of the metal rods are used to tighten and lock the adjacent bearing plates 2 and the flange plates 3 to fix the two clamping claws. When disassembling and repairing the bracket, pull out the positioning step pins 6, and then, the handles of the two clamping handles 4 are loosened upward to release the locking state of the bearing plate 2 and the flange plate 3, so that the two clamping claws can be disassembled. The entire disassembly and assembly process of the clamping claws does not require screwing, and the calibration steps are simple.

[0024] The metal rods of the two clamping handles 4 have sufficient length to freely pass through the corresponding limiting slots 5 to prevent the adjacent flange plates 3 from being stuck.

[0025] like Figure 4 and Figure 5 As shown, guide slots 7 are provided on the outer sides of the two flange plates 3 between the corresponding two limit slots 5, and circular ring portions matching the guide slots 7 are integrally installed on the outer sides of the two positioning step pins 6. The positioning step pins 6 can be pushed horizontally along the guide slots 7 and aligned in a straight line with the tightening position of the adjacent bearing plates 2, so that they can be quickly put into place.

[0026] like Figure 2 and Figure 4 As shown, positioning holes 8 are provided on the upper surfaces of the two bearing plates 2 at positions corresponding to the two clamping handles 4. The two positioning holes 8 are respectively matched with one end of the two positioning step pins 6. After the positioning step pin 6 is aligned with the positioning holes 8, one end thereof falls into the positioning holes 8, and the annular ring falls into the guide groove 7 to be supported. In addition, there is a shearing effect that moves the bearing plates 2 and the flange plates 3 away from each other, and they respectively press against different positions on the outside of the positioning step pin 6, and the positioning step pin 6 is locked by friction.

[0027] like Figure 2 and Figure 3 As shown, reinforcing plates 9 are fixed to the lower surfaces of the two supporting plates 2. The outer sides of the two reinforcing plates 9 have arcs that are consistent with the edges of the positioning holes 8, which can increase the structural strength of the two supporting plates 2 at the positions of their positioning holes 8 to improve the overall supporting performance of the bracket.

[0028] like Figure 1 and Figure 2 As shown, the ends of the two supporting plates 2 that are away from each other are fixed with a rotating shaft 10 that is rotatably connected to the adjacent vertical plate. The two rotating shafts 10 are coaxial and can be actively rotated by using driving elements such as brake motors to change the inclination angle of the supporting plates 2 with the horizontal, so that the clamping claws have freedom on the rotating shaft.

[0029] like Figure 1 and Figure 2 As shown, a coupling 11 in a "U"-shaped structure is fixedly installed between the outer sides of the two rotating shafts 10, so that the two rotating shafts 10 are fixed and can rotate synchronously.

[0030] The working principle of the utility model is as follows: during installation, the base 1 is fixed at the designated position of the production line, the two bearing plates 2 drive the two clamping handles 4 upward, and the handles of the two clamping handles 4 are pulled upward and loosened, and the two flange plates 3 are respectively attached to the upper surface of the corresponding bearing plates 2, and the metal rods of the two adjacent clamping handles 4 are clamped with the limiting grooves 5. After tightening, the adjacent bearing plates 2 and the flange plates 3 are inserted with the positioning step pins 6, and then the handles of the two clamping handles 4 are lowered, and the two ends of the metal rods are respectively tightened and locked to lock the adjacent bearing plates 2 and the flange plates 3 to fix the two clamping claws.

[0031] When disassembling the maintenance bracket, pull out the positioning step pin 6, and then pull the handles of the two clamping handles 4 upward to loosen the locking state of the bearing plate 2 and the flange plate 3, so that the two clamping claws can be removed. The entire disassembly and assembly process of the clamping claws does not require screwing, and the calibration steps are simple.

[0032] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
